Title:
METHANOL PRODUCTION METHOD AND METHANOL PRODUCTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004464
Kind Code:
A1
Abstract:
According to the present invention, a method for producing methanol using carbon dioxide and hydrogen as starting materials includes a step (A) for combining the carbon dioxide and the hydrogen to obtain a makeup gas, a step (B) for combining the makeup gas, after the pressure thereof has been raised, with a recycled gas recovered from an outlet gas from a synthesis reactor to obtain a synthesis reactor supply gas, a step (C) for preheating the synthesis reactor supply gas by means of a heat exchange in which the outlet gas from the synthesis reactor serves as a heat source, and a step (D) for supplying the preheated synthesis reactor supply gas to a synthesis reactor and bringing the preheated synthesis reactor supply gas into contact with a catalyst to synthesize methanol.
